If you get nothing after you ..."did try a non amplified one in the attic and no stations receivable" I wouldn't expect anything different if you moved it up to the roof. There is just something wrong with your set-up, assuming your TV is less than 16 years old.
We all assume you: have a tv or a stand-alone receiver that is designed to tune "off-the -air" broadcasts; Have the external antenna's "F" connector with a straight center conductor "stinger" properly inserted and tightened to the antenna connector; Have a balun at the antenna to change from 75 ohm catv coax to 300 ohm flat wire antenna connection; Know how to "Autoprogram" your tv to register the various channels. You haven't told us what kind of "non-amplified" antenna you tried. Do you know which way to point it, or which is the front of the antenna? (if it's directional?)
I am in Summit, only watch Broadcast TV beside internet. Most broadcasters moved to UHF which has much less coverage than VHF. But I think ABC is still in the RF channel 7 spot, so it would be easiest to get, and if you are lucky to have an older TV antenna with VHF low band, WJLP broadcasts from NYC on RF Channel 3! I think there is another, perhaps Channel 13 on RF channel 12 now? You can find out here or on some of the various websites. But you SHOULD get several channels. I am only 6 miles east of you. I get 2,3,4, 5,7, 9, 11,13 14, 21, 23?, and about 8 more. With all the "sub" channels, the total is close to 72 or more.
Good Luck, keep at it.
